S1T2418D02 TONE RINGER

TONE RINGER WITH DRIDGE DIODE INTRODUCTION The S1T2418G01/D02 is a monolithic integrated circuit telephone tone ringer with bridge diode. When coupled with an appropriate transducer, it replaces the electro-mechanical bell. This device is designed for use with either a piezo transducer or an inexpensive transformer-coupled speaker to produce a pleasing tone composed of high frequencies (fH1, fH2) alternating with a low frequency (fS) resulting in a warble frequency. The supply voltage is obtain.

S1T2418D02 Features

* Built-in full wave bridge diode rectifier

* Low current consumption, in order to allow the parallel operation of 4 devices

* Few external components

* Tone and adjustable switching frequencies by external components

* High noise immunity to current hysteresi
